SHOE HEEL.

' Application filed May 2,

To all whom t may concern.'

Be it lrnown that I, JAMES B. HANLEra citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Shoe Heels, of which the following is a specification. i

One object of my invention is to make a resilient heel structure for shoes which will be an improvement over various known forms vof rubber heels;the construction of my 'improved heel being such that it will absorb shocks and at the same time will be extremely durable land when worn upon. a shoe will enable a person to walk more easily and comfortably.

Another object is toso construct my im-A proved heel that it canbe easily manufactured and attached to or detached from a shoe.

These objects,` and other advantageous ends which will be described hereinafter, I attain in the following manner, reference being had to the accompanying drawings in which- Figure -1 is a side elevation showing my improved heel attached toa shoe,

Figure 3 is a sectional plan view taken on the line 3 3 of Figurel 1v andl drawn on a slightly enlarged scale,

Figure 4 is a section taken on the line 44 of Figure 3,l Y'

Figure 6 is an inverted plan view of the attachment plate with the plungers mov-` ably secured thereto, i Figure 7 vis a detached top the lift-retaining band,

13. This plate at one end has aA recess 14 as shown in Figures 3 and 6 and the outer o surface of the flange 11 is concaved in vertical' cross section as shown at 15 in Figures 4 and 5. The provision of the flange 11 produces a space 16 above the surface` 12 and another space 17 below the surface 12; both of said spaces being boundedby the flange 11. Y The plate 10 has holes 18 through 'which slide the stems 19 of plungers 20. v

The lower end 21 of the plungers, which are of greater diameter than the stems 19,. have fianges 22A and cavities in their bottom surfaces inverted cups as shown in Figure 9. The upper ends of the stems 19 have annular grooves 24 into which are adapted tor be sprung split resilient rings 25 by 'forcing said rings over the upper tapered ends 26 of the stems 19. v i,

Coiled springsv27 surround the stems 19 so as to form` and parts- 21 of thel plungers20 'and have` their opposite ends in respectiveengagement with the surface 13 of theplate 10 and theupper surface of the `flanges 22 so as to move the plungers downwardly. The upper part of the plate 10 has depressions y28 into which the rings 25 move due to the action of the springs 27; said rings abutting the inner parts of the depressions 28V and l,

thereby limiting the downward 'movement of the plungers.'

are thinner at their Aends than at parts be- The springs 27 are -prefery ably made by coiling lengths of wire which tween the ends so that theend portions of the springs can more easily fleX than the in termediate portion thereof.`

A lift29, which yis'preferably made of rubber, has a continuous flange 30 which projects upwardly fromthe bottom portion 31. This flange 30 of the lift is adapted to engage the concave surface ofthe flange 11 ofthe attachment plate and a clampingv band 32 surrounds the outer surface of the lift flange 30 and is adapted to compress said flange 30 and hold it within the concavity of the flange 11 of the attachment plate. The clamping band 32 maybe made of a strip ofresilient metal having its `end portions 33 adapted to be kpositioned within the recess 14 and a clamping Ymember 34 is adapt-ed to engage the end portions 33 of the clamping band and to4 move them toward each other while within the'recess 14so as f the attachment plate and passing between the end portions 33. The outer surface ofy the end portions 33 are preferably slightly indented as shown at 36 and theclamping member has a portion 37 as shown iii Figure 4 whiclrenters the indentation 36 andfwhen the clamping member V3e is screwed inwardly the end poi-tions 33 will. be moved toward.

eacli other toi form the clamping action. of

the band 32 so as tocoinpi'ess the lift flange 30 andtherebysecure lthe llift to the attachment plate l0.4

The lowerends of the plungers `20 are adapted 1to1 engagewt'heuppervsurface 33v of the portionl `of theilift soi' as to normally #hold-tliehporti-on: 3l-of the lift under .i

a slight tensioni-glia portion rof lthe rubber of thelift-enteringfbthe `cavities Q3 of the plungers 20 so asl to prevent the lower ends of the plungersfrom shifting laterally fromv their predetermined normal positions. The" heel can be attached to the body por tion39-of the Ashoe by means of screws 40 before the-lift and* clamping band `are placed in position; said screws extending through i the 'attachment plate and into the 'bot-tom of the-bodyportionf39 of the shoe.l Thev outer surface-of the portion 31 of the' lifti's preferably made slightly convex with out anysharp edges so as to conform to theshape -of the bottom-fof thehuinan heel and during walking. action r the shocks will be taken up jointly by thespringLpressed plungers1 and 1 :also -by the-resilient'- character of the lift; theplungersby being 'arranged as clearly shown-iiiFiguref` areso disposed that' Athey will. resist` shocks imiparted at practically- =every lportion ofthe heely and dueito f this disposition of the -plungers and the yielding-actionf-of the `lift both due-to its own resiliencyiancbto the-resiliency provided by the springs, the bottom portion` 31 will .not readily-wear out-to dcstroythe shape fof the'fheelas--do tlielsolid rubber heels made-prior to my invention.

The clamping band 32 can be made of a Width substantiallysimilarA vto the width of the-flange lltof the attachment: plate with holes therein; a lift having Iits bottom.

and?y this band on-its outer surface-can be colored to correspond ywith the color :of the body portion'of the shoeland iif desired the lift -canI-be made ofI a corresponding color so as to present faneat.appearance.-
